Finally managed to have all tools and info in one window with the help of tmux. The following data is now available while logging QSOs (bottom of the screen, left to right):

* selected band on the PA
* PEP/Average Power of last transmission
* SWR during last transmission
* temperature reported by the PA

* temperature/humidity inside the rack
* outside temperature/humidity

Data of the power amplifier is queried via a serial port, temp/humidity is gathered with two DHT22 sensors via GPIO pins.

This won’t win a beauty contest but it works ;) A 3D printable power pole distributor which is cheap and rack mountable. The top is not my design, the bottom is a remix of two other designs.

Thanks to Bill, AK3Q, my Hermes lite 2 now has a interface for the Hardrock-50. He gave them away for free to a lot of people. Highly appreciated, very happy!

After I finally connected my garden house to the GAN (garden area network) I am now starting a little experiment. Moved my Hermes Lite 2 SDR into the garden house, added a network enabled remote antenna switch and put everything in a plastic box on the inner side of the wall, right there where my antennas are placed outside. This is now a remote operated station but still on the property with shorter coax cables, better grounding options and reduced pot. lightning damage. Feels weird but fun.

There must be a better solution than this. Any ideas how I could fix the fan on the heat sink?

Today I once again fell in love with the 817. With just 5w I was able to work multiple European entities on 2m SSB. At home my VHF radius is more or less 50km. The QTH was very nice and the weather optimal.

SDR TRX + VPN = Awesome! I added a rpi3 to my home network, moved it into the DMZ, set up some firewall rules and installed Wireguard on the pi. With the SDR software on the laptop I can now dial into my home network and establish a connection with the Hermes Lite. Just had my first remote SDR QRP QSO with F4IXL/P and am pretty impressed how nicely it worked.

The DIY 1/4 wave 20m vertical works like a charm! A very nice antenna for unbeatable 20€ which gave me good reports from G and PT during the tests.

Today the QRP guys tri band antenna kit finally arrived - after 2,5 months of USPS shipping. This one will be compared with the HF-P1 very soon.

After many years of inactivity I finally was out for a proper bike ride. One side quest was to find a nice place for portable HF operations. This place looks good: bench, tree, solid post for antenna mounting and no surrounding hills etc.

Today I did a little hike, was on the Schweinsberg tower and was rewarded with a great view and some nice QSOs 🙂

Welcome to Germany:

That's what happens when your mother accidentally activates "mobile data" on her cell phone.

Fun Fact 1: The 50MB was generated by ads from a free games app.

Fun fact 2: There is of course 19% VAT on top of that.

50MB. 450 €. 2021.

Ok, I promise: This is the last pic of the Hardrock 50 I‘ll toot :)

Last night I completed the build of the Hardrock 50. Thanks to the awesome documentation it was very enjoyable and easy to do.

I finally managed to work 100 confirmed entities :) My new adventures will be working QRP with my recently purchased FT-817ND and building a small PA for the times I need a small boost.
